ABSTRACT In this paper, a hybrid method (hybrid PMM-MoM
method) is presented for the effective and accurate analysis of finite periodic
structures. This method divides a finite periodic structure into two parts. The
inner part of an approximate infinite periodic structure is analyzed by
periodic method of moment (PMM); the outer part is then analyzed by method of
For the finite periodic structures, the accuracy of the new method is much
better than that of the pure PMM, and is almost the same as that of pure MoM.
Because pure PMM uses the periodic boundary conditions, it takes much less
memory resources and computation time. For hybrid PMM-MoM method, because the inner part is calculated
by PMM, the calculation work concentrates on the outer part. Consequently,
compared with the exact MoM, the new method saves much more memory
resources and computation time, which provides a drastic reduction of unknowns.
